The simplified stability test may be used on vessels under 100 gross tons, not more than 65' in length and carrying between 7 and 150 passengers. For subchapter T boats carrying more than 6, but less than 50 passengers, the test is required when the vessel's stability is questioned by the Officer in Charge, Marine Inspection (OCMI). Subchapter T boats with more than 49 passengers must perform the simplified stability test or complete an inclining experiment. An inclining test requires the services of a naval architect. 

Basically, the simplified stability test consists of fully loading a vessel in its worst case condition. We calculate simplified minimum test moment and calculated test moment to verify that the simplified test is valid. As weight is moved across the deck, three methods are used to determine the vessel's stability: measure degree of incline, visual sighting of the immersion mark, and calculations of the weight movement.

We have performed many stability tests for vessels operating on non navigable waters, as required by the State of operation. We have performed many stability test for vessels operating in navigable waters with the vessel's OCMI.

We provide all equipment required to perform the stability test.
